Enhancements include making it easier and more apparent how to add photos to an order and how to place an order. In addition, the metadata fields were fine-tuned and improved to increase the discoverability of the photos. Other minor changes were made to provide streamlining and consistency to the interface.

S. Navy submarines to collect data about the Arctic Ocean, has been highlighted in two articles in the Spring 2015 issue of Witness the Arctic published by the Arctic Research Consortium of the United States (ARCUS). The first article, Teaching an Old Submarine Data Collection Program New Tricks, provides a high level description of the project and the data available including Arctic Ocean bathymetry, hydrography, and sea ice draft. The second article located below the first one, A Labor of Love Brings Together Civilian Scientists and the U.S. Navy, provides a history of how and why the SCICEX program came into being. For more information on this program, see the SCICEX Web site.

In addition, all sea ice extent values for the entire time series have been made available via one comma separated value file: masie_allyears_extent_sqkm.csv. There is one value per day for the entire Arctic, as well as one for each of the 16 MASIE regions. NOAA@NSIDC publishes this popular product in collaboration with the U.S. National Ice Center in Suitland, Maryland. For complete information, visit the MASIE Web site.

The September 2014 minimum KMZ file has been updated to use final instead of near-real-time data, and the March 2015 maximum KMZ file has been added to the time series. To view these, and other, Google Earth files, visit the NSIDC Data on Google Earth web page.

This collection was compiled by the World Glacier Monitoring Service (WGMS) who collect and disseminate standardized observations on glacier fluctuations such as length, area, volume, and mass. This special collection focuses on photographs of glaciers for which long fluctuation series are available, some of them dating back to the 18th century. The photos were assembled from the WGMS archive, from contributions from WGMS principal investigators, and from various other sources that provide freely available data. To view the new collection, visit the Glacier Photograph Collection search interface and select “WGMS Glacier Photographs” from the Choose a Collection drop-down list.

These masks are now available from the NASA NSIDC DAAC as a stand-alone data set: Polar Stereographic Valid Ice Masks Derived from National Ice Center Monthly Sea Ice Climatologies. The valid ice masks are based on the National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format data set, a NOAA@NSIDC data product.

Known as MASAM2, this sea ice concentration is a blend of two other daily sea ice data products. First is ice coverage from MASIE, the Multisensor Analyzed Sea Ice Extent product, at a 4 km grid cell size. Second are ice concentrations from the Advanced Microwave Scanning Radiometer 2 (AMSR2) at a 10 km grid cell size. MASIE and AMSR2 data are blended together to take advantage of the best features of both products. MASIE, based on U.S. National Ice Center (NIC) analyses, is more likely to be accurate in showing where ice is present than AMSR2 due to the use of multiple sensors and quality control of the data while the AMSR2 sea ice concentration product gives concentration information not available from MASIE alone. This prototype MASAM2 product currently covers only 27 months, July 2012 through mid-November 2014, but it will become a daily product if there is demand for such a product.

Beginning 01 January 2008, the data will include a pole hole that covers 0.029 million sq km rather than the previous pole hole of 1.19 million square kilometers. In addition, an error in the pole hole used for data from 01 July 1987 to 31 December 2007 was corrected. These data now uses a pole hole of 0.31 million sq km rather than 1.19 million sq km. The varying pole hole sizes correspond to the orbit inclination of the satellite used to collect the input data.

The new masks are derived from the National Ice Center ice chart monthly climatologies which define more realistic boundaries for ice presence based on recent trends. These new masks have been applied to all historical data. Lastly, the extent values in the daily extent .csv file have been rounded to three decimal places instead of six because anything further than three digits is outside the precision of these data. More information can be found on the Sea Ice Index documentation Web page.

The International Ice Patrol (IIP) Iceberg Sightings Database has been updated through the 2014 iceberg season. The IIP has been collecting information on iceberg activity in the North Atlantic since 1911. This database contains the data from these sightings starting in 1960. The IIP data files include latitude and longitude of sighted icebergs, coded iceberg size and shape class, and date and time of the sighting. For more information on this data set and to access the data, please visit the International Ice Patrol Iceberg Sightings Database web page.
